design patterns - Django: ForeignKey() or ManyToMany() in this case? Or, other? -

-

I have a model that is something like this: 

  class return authorization (models Modod): Custom_id = models.CharField (max_length = 40) class RMAAPILog (models.Model): return_authorization = model. ForeignKey (ReturnAuthorization)

If I delete () / Strong> A return authorization, I can not remove it all RMAAPILog () s which are related to it in this case they are removed. There may be several attempts to obtain RMA from external APIs (many RMAAPILog () s ReturnAuthorization () , but only one return authorization () for each Definitely RMAAPILog () because it is an attempt to authenticate specific ReturnAuthorization () . What would be better way to do this, or am I thinking all the wrong about it? >

c# - TypeConverter in propertygrid only converts from string, not to -

-
When the property grid is reached, only the conversion mechanism (often called) is called "Foo!" Returns the property string in the grid when I click to edit I get an exception Type.oo. Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from. I think that when I want to edit this object, it will have to be converted from foo to string, and when the editing ends. Public class FooTypeConverter: StringConverter {public override object ConvertFrom (ITypeDescriptorContext Reference, CultureInfo Culture, Object Value) {New Foo (string) value); } Convert the public override object (Type the ITE DiskText Contact Reference, CultureInfo Culture, Object Value, Type Type) {Return "Foo!"; } Public override bool CanConvertFrom (ITypeDescriptorContext reference, type source type) {back true; } Public Override Bull CanConvertTo (ITypeDescrip...
